Referring to the drawings of Figs. 1 to 4, I is v a lipstick container adapted to hold a. lipstick casing cover 2 thereon. The container Ihas. a. shoulder base 3 in which the lower end of the. container I fits and is held. 4 representsa cartridge containing lipstick paste or rougeand.

having an open ended and fiat portion 5, and-anopen ended inclined portion 6 adapted to form.

two diverging frames for containing the lipstick material at the working end, so as to provide aprojecting ridge of lipstick material transverse of the cartridge at the junction of the two planes similar to the ones shown in my above referred to applications. I

The cartridge 4, Figs. 3 and 4,- as shown'in some of the above pending applications, has a" rotatable circular closure I at the lower end rigidly attached to a feeding screw 8, adapted when the screw is turned to force the plunger 9 up or down. Lipstick paste or rouge I is mounted in the cartridge above the plunger and may be forced toward the working end of the cartridge as the plunger is slowly fed upwardly when the screw 8 is rotated with respect to the cartridge. The end closure plate 1, to which the screw 8 is attached, is adapted to fit into the counterbored' portion II in the lower ends of the cartridge which is then spun over the bottom edge of the closure plate I so that the plate and screw may rotate with respect to the cartridge 4, but be prevented from longitudinal movement with respect to the cartridge 4. I

In the form shown in Figs. 1 to 6, I mount axially on the bottom end of the plate I a noncircular block I2 having a hole I3 therethrough. The block I2 may be fastened on the outer surface of the plate I by soldering, welding or any otherblock and projects slightly on both ends from the side of the block. This block, with its slightly yielding projecting portions of rubber or other material, is adapted to be positioned inside a hollow receiving tube I5, the outside Surface of which is adapted to be soldered or otherwise fastened to the inside of the base 3 for permanent location. The base 3 has a bored-out portion I6 in which is located the lower end of casing I which is permanently fastened therein.

From the above it will appear that the cartridge 4 containing its base and feeding mechanism and driving block I2 with protruding friction portions of material I4, may be inserted in the casing I and readily removed therefrom, and when inserted therein in the position shown in Figs. 1 to 4, a driving relationship will exist between the square driving block I2 and the square hollow tubing I5. that theprojections of material I4, being of rubberor otheryielding material carried bythedrivi'ng block I2, willengage the inner walls of two opposing. inner surfaces of. the drivingtube I so that the cartridge with its driving block I2 will be frictionally, but sufficiently, held in place by thev friction material ld'serving as a frictional holding means to retain the cartridge in' place in the casing I until removal is desired. At the same" time, when the cartridge is in place-in the cartridge I, thedriving' block I2 will be in drivingrelationship with the hollow tube I5 suchthat' rotation of the" cartridge 4 with respect to the casing,Iandicasingxbase 3-, will serve to; provide rotative' drive through. the tube I5 and block I2 to the endof the'closure'plate' 'I having fixedto it driving screw 8 on which isenga'ged the plunger 9; The1plunger-9 is-n'otched to'contact'splin'e' I? mounted longitudinally against-the'inner wall of the cartridge i. This non-.rotati've connection be tiweenplunger 9 and thecartri'dge 4, by virtue of the'spline I1 and its keyway'connection in" the plunger 9; which prevents-rotation ofthe'plunger with respect'to the cartridge 4, causes the latterto-movelongitudinally in'the' cartridge 4 when thescrew 8' is" rotated. This movement of the plunger" up or' down is caused whenever rctative movement of the screw 8 and its' driving block I 2. with respect to the cartridge wall 4; is effected; It is thus seen that in this form I'provide acartrid'ge which maybe yieldingly and frictionally held in'place and in driving relationship to'the lipstick case adaptedto hold the removable cartridg'eand yet provide a convenient detachable driving-connection for the cartridge with respect to the lipstick-case.

In Fig. 5 I have shown a modified form from that shown'in Figs. 3 and 4" inwhi'ch the hollow drivingitube I5' is surrounded by: thesection of'a circular tube I8, the inner diameter of the tube It adapted to fit the large diagonal of the driving' tube I5'and'surround' thesame. The outer part'of' the tube I8 is adapted to fit within the lower end of the casingv I and be soldered or fastened thereto, and. thus aid in locating thehollow driving-tube I5.-

Fig. 6 merelyshows a perspective of the driving block I2 rigidly attached to the feeding mechanism of the cartridge with its rubber projections Ilextending from the opposite flat surfaces-of the driving block.

Figs. 7' to show modified formsof detachable driving mechanism for-the lipstick cartridge. In this form the description is-thesame as that of Figs; 1 to 4' except that'the squared driving block I9 fixed to the bottom surface of the end It will be further observed closure plate Ia, in turn fastened to the feeding screw 8a, instead of having a frictional rubber rod extending through the same, is provided with four bevelled notches 20 in one plane at the corners of the square driving block. Also, just below these notches the extreme ends of the edges are bevelled at 2|. This block is soldered or otherwise fastened to the end plate Ia in the same manner as described for the other views above in connection with the squaredidriving block. In these figures I provide for the driving block I9 to be driven by a hollow square tubing 22, the inside dimensions of the hollow tubing being such as toreadily receive the driving blockv I9. Two opposite corners of the tubing 22 are slotted at 23from extreme peripheral dimensions sufficiently; inwardlyjto come across the inside cornersof, the tube. One of the other corners of the driving tube 22 is notched partially at 24 and in these three notches is adapted to pass a hairpin spring'25, the closed end of whichis adapted to fitiin the notch: 24 so asnot toproject beyond the edge -24a of the hollow: tube22 at this edge. The legs'of the hairpin spring 25 are positioned in the slots 23 of the hollow-tube 221. so that' the spring sides of the hairpin project'across'the inside opposite corners of the hollow. tubing to form a latching means to latch. the drivingblock I9 It is seen-that the lower extent of" container sheath I; in combination-with thesquared hollow receiving tube 22, provides aconstruction very similar, in general'form', to the-ring shown in Fig. 5; Under such mounting-conditions the lower innersurface of'sheath I in contactwitlr the corners of the square block such as 24a, 10, provide means for holding the hairpin'spring 23 in the slots of the squared'tub'e: Withthis arrangement insertion of the-block I9 into the lipstick casing, and therefore into the square re ceivingtube 22, through the action of the bevels 2I of said block causes thelegs of the hairpin spring 23 to yield outwardly from the center-of the squared block in the provided slots 23; Further insertion ofthe'block'then allows the hairpin springto'latchingly engage the notches 20, as previously described.

In Figs. 11 to 16 I have shown a further modification of detachable driving means for the lipstick cartridg e.- In this form'the cartridge'and lipstick case is the same as inthepreceding 29 in its two opposite walls, and also has two.

opposing holes-30in the corresponding wallsiust above the notches. I mount a U-shaped sprin 3| in the notches-so as to goacross the lower end of the tube 28' in the" notches, and this U-shaped spring has two opposing projections 32 which are adapted to be positioned in the holes 30, the projections 32 adapted to project inside the inside surface of the hollow tube 28. The spring is mounted in place before the hollow tube is fastened to the bored-out portion of the base 3b and when in place the U-shaped spring, with its projections 32, serve as yielding latching means which are bevelled at the opposing ends. Thus it will be seen that when the driving block 2% of Fig. 13 is forced into the hollow tube 28 the spring projections 32 in U-shaped spring will be forced outwardly, allowing the driving block to be pushed completely in place when the latching projections 32 will engage either of the two sets of opposing depressions 27' in the driving block 25. By this construction I provide a detachable driving relationship between the driving block on the bottom end of the cartridge and the driving tube mounted on the bottom of the inside base of the casing. When the block is in position the Ushaped spring with its projections extending through the holes in the driving tube cooperate with the driving block depressions as a latching means to hold the block and cartridge in place, and the non-circularity of the receiving tube 22 and the driving block 25 provides driving connections between the base and feeding screw for the lipstick cartridge.

From the above description it will be seen that I have provided a novel, cheap and practical detachable driving means for a lipstick cartridge for coupling the same to the casing, which will serve as a driving means for the mechanism of the cartridge. In the manner shown I form a practical but cheap construction for accomplishing this end. I have been able to eliminate considerable machine work caused by forming the riving connection out of square, square-sided or non-circular rod and corresponding polygonal or non-circular hollow tubing adapted to telescopically fit so as to provide a driving connection without too much cost for machine work. I have also provided a practical method whereby these non-circular driving means may be frictionally held together to retain the cartridge in place in l the casing, and also a form in which they may be practically held together by yielding spring means, still retaining the driving connections capable of being formed from inexpensive stock.
